I've been using Spotify in my 2017 ford Fiesta mk7 since I bought it, in January 2018 Spotify was removed from apps usable in applinks and I have to revert to a previous version of Spotify to continue using it. That wasn't a problem until a few days ago. Everytime I go into SYNC apps and select Spotify I get a message saying "Spotify not authorized" and the app doesn't open. I have tried defaulting my Sync settings and a master reset but have no idea what the issue is. Can anyone help my situation? Thanks
